Definitions
- the invention relates to a switching and driving range selection device for a semi or fully automatic gear change transmission of a motor vehicle correspond to the features listed in the preamble of claim 1 and 3, respectively.
- a switching and driving range selection device of the aforementioned type is known from DE-A 40 06 653.
- the driving range selection device with which different switching sequences can be preselected by the driver, such as, for. B. a fully automatic operation, manual operation, a reverse travel position, a neutral position, etc., is optionally designed as a rotary or button switch.
- the switching device via which the driver issues switching commands to an electronic control unit in manual or semi-automatic operation of the gear change transmission, is designed as a steering wheel switch or as a manually operated console switch. From the speed, load and acceleration values in connection with the engine map, the control unit determines the most favorable gear for the respective driving state and visually indicates it to the driver.
- the driver By actuating the shifting device in a first movement level, the driver triggers the shifting of the recommended gear. If he moves the switching device in a second movement plane, which runs transversely to the first movement plane, manual up and down shifts of the gear change transmission are triggered by individual gear stages. In addition, downshifts of the transmission can still be made with the help of an Accelerator pedal provided kick-down switch are triggered.
- the disadvantage of this device is that the operation of the switching device designed as a steering wheel or console switch requires special attention from the driver, it being impossible for both hands to remain on the steering wheel.
- this foot switch can be used to trigger manual shifts by individual gear steps or automatic shifts to the gear step that the control electronics evaluates as optimal.
- the driver can concentrate fully on the traffic situation and can keep both hands on the steering wheel during a manual gearshift or the triggering of a gearshift in an automatically preselected gear.
- a combined shift and driving range selection device with a selector lever movable in two shift gates is known.
- selection positions for fully automatic operation, upshift limitation levels as well as a park, reverse gear and neutral position of the gear change transmission can be preselected.
- the selector lever can be moved via a cross alley into the second shift alley, in which the gear change transmission is gradually moved up or down by hand. is downshifted.
- Manual shifting of the gear change transmission also requires increased attention from the driver, during which he can only steer the vehicle with one hand.
- a combined driving range selection and switching device which has a selector lever which can be moved in an aisle running in the longitudinal direction of the vehicle.
- These selection positions include a position for manual operation of the gear change transmission, in which the gear stage last shifted by the automatic is maintained.
- the selector lever In the manual position, the selector lever can be moved by hand in two different directions transversely to the selector gate, as a result of which the gear change transmission is gradually shifted up or down.
- the driver has to look for the appropriate position on the selector lever in which a manual shifting of the gear change transmission is possible, so that his attention is distracted from the traffic. Since the driver has to carry out the appropriate gearshifts by hand, both hands cannot remain on the steering wheel.
- the foot switch has a rocker switch which is movable about a horizontal pivot axis and the rocker halves of which interact with contacts for upshifting and downshifting, respectively.
- the rocker switch can be designed so that the driver senses through a haptic signal that the switching command has been accepted by the electronic control unit.
- the rocker switch can be provided with means which allow the rocker switch to return to its neutral position after each shift command before a further shift command is entered.
- the foot switch is designed as a pressure switch, the actuation duration of the pressure switch being determined via a timer and this being assigned to a desired up or down switching. It could be downshifted, for example, by briefly tapping the pressure switch, while holding the pressure switch in its actuation position for a longer time leads to an upshifting of the gear change transmission.
- the driving range selector device should have a selector lever movable in a selector gate, the selector lever in the selector gate positions for fully automatic operation AS, manual operation M, operation ASM, in which, when the foot switch is actuated, it is determined directly by an electrical selection circuit optimal gear stage is switched, for a neutral position N and for a reverse range R.
- the motor vehicle is operated essentially in the positions fully automatic operation AS, operation with direct shifting to an optimal gear stage ASM and manual operation M, these positions preferably being adjacent to one another, so that only short actuation paths of the selector lever and little attention from the driver this dialing process are required.
- the selector lane can be L-shaped, the positions for fully automatic and manual operation, shifting of the optimal gear and neutral being arranged in succession in a common selector lane and one position for the reverse driving range on End of an adjoining cross alley is arranged.
- the forward and reverse driving ranges are thus separated from one another, and incorrect operations can therefore be avoided.
- the first selector lane to which the forward travel positions are assigned can be arranged transversely to the direction of travel thereof in the motor vehicle.
- a shift of the reverse gear should be triggered manually with the foot switch in a reverse driving position of the driving range selection device.
- This reverse gear of the gear change transmission can only be switched when the motor vehicle is at a standstill, and the output of this switching command from the electronic control device is expediently suppressed via a safety device as long as the motor vehicle is driving forward.
- the gear change transmission can be downshifted by a single actuation of the foot switch in fully automatic operation by one gear step.
- Such a design of the device has the advantage that the gear change transmission can be downshifted by one gear step before overtaking and before driving up slopes without any particular shift effort. This downshift can be canceled according to claim 9 by repeated actuation of the foot switch or after a time function.
- 1 denotes a gear change transmission, which can be designed in countershaft or planetary design.
- This gear change transmission is driven by an internal combustion engine, which is not described in any more detail, an automated drive clutch being arranged between the internal combustion engine and the gear change transmission 1 when it is designed as a countershaft construction.
- the gear change transmission 1 has shift cylinders 2 for its gear shift, which interact with shift clutches arranged inside the gear change transmission 1.
- Solenoid valves 3, a main switching valve 4 and switching valves 5 and 6 are assigned to these switching cylinders 2 and further switching or selection cylinders, not shown in the drawing.
- These valves 3 to 6 are controlled electrically by an electronic control unit 7.
- Compressed air is made available in a pneumatic accumulator or pressure vessel 8 and is supplied to the switching cylinders 2 via the electrically controlled valves 3 to 6.
- a hydraulic fluid can also be provided as the actuating means instead of compressed air.
- An electrical line 9 connected to the electronic control unit 7 transmits measured values and switching signals to the electronic control unit 7, wherein speed sensors are connected to this electrical line 9, specifically a speed sensor 10 for determining the speed of the internal combustion engine, a speed sensor 11 for a transmission input speed and a speed sensor 12 for a transmission output speed.
- the electronic control unit 7 issues switching commands to the valves 3 to 6 via a further electrical line 13.
- a steering wheel 14 with a steering column 15 is arranged in a driver's cab or a passenger compartment of the motor vehicle. Furthermore, in the footwell of this driver's cab there is an accelerator or accelerator pedal 16, which adjusts a throttle valve (not shown) for gasoline engines or a control rod of an injection pump for diesel engines as a load sensor.
- the accelerator or accelerator pedal 16 can be mechanically coupled directly to the throttle valve or control rod or an electronic coupling (E-gas) is provided.
- the accelerator pedal 16 also interacts with a kick-down switch 17, which triggers a downshift of the gear change transmission 1 when the accelerator pedal 16 is actuated quickly via the electronic control unit 7.
- a driving range selector 18 designed as a console switch, the selector lever 19 of which serves to preselect certain driving programs, is arranged in the driver's cab of the motor vehicle.
- a display device 20 which is also connected to the electronic control unit 7, the currently engaged gear of the gear change transmission 1 is displayed, and a recommended optimal gear level is displayed in the ASM position of the selector lever 19 in parallel.
- a switching device 21 is arranged in its footwell.
- This switching device 21, which can be operated by the driver with his left foot, is also connected to the electronic control unit 7 and, in the position M for manual operation of the driving range selection device 18, triggers a step-by-step up and down shifting of the gear change transmission 1 by a different operation .
- Two different variants of the switching device 21 are shown in the drawing.
- the switching device 21 should have a rocker switch 22 which has a central pivot axis 23. If the shift paddle is pressed on a rocker half 22A by the driver, a corresponding closing of a contact (not shown) leads to an upshift of the gear change transmission 1 by one gear step. In a corresponding manner, when a rocker half 22B is stepped on, the gear change transmission 1 is shifted down by one gear.
- the gearshift is also shifted into a gear which the selection gearshift considers to be optimal by actuating the rocker switch 22.
- the gear change transmission 1 in the position AS of the selector lever 19 is controlled fully automatically on the basis of speed and load signals, the driver can do so arbitrarily interrupt this control for a certain period of time before overtaking or when driving uphill. In this case, he only has to briefly actuate the switching device 21, then the gear change transmission is downshifted by one gear. After a certain period of time, this operating state of the control device is automatically canceled again, or provision can be made to cancel this operating state by stepping on the rocker switch again.
- the switching device 21 is shown in dash-dot lines. It is a pressure switch 24 which is connected to the electronic control unit 7 via a timer 25. Depending on the duration of actuation of the pressure switch 24, which is determined by the timing element 25, it is determined whether it is a desired upshift or a desired downshift of the gear change transmission 1.
- the drawing shows that with the switching device 21 designed as a foot switch 22 or 24 the driver can issue switching commands to the electronic control unit 7 in a simple manner without being distracted from concentrated driving. It is particularly advantageous that the driving range selection device 18 is arranged separately as a console switch, via which no switching commands are issued. Experience has shown that a combination of switching device 21 and driving range selector device 18 within one operating lever frequently leads to incorrect operation and requires the driver to be very attentive.
